  • Patent number: 11389992
    Abstract: The subject matter proposes an automated compact depackaging system. The depackaging system includes a receiving hopper, a vertical depackager, dumpsters and a sedimentation unit. The vertical depackager simultaneously removes and cleans packaging materials and the materials that exit the system are clean and organics free. The system also includes a dosing device for dosed discharge of waste or bulk material into the hopper. The hopper may also receive the organic wastes directly from trucks. The dosing device is fitted with metal to identify metals in the bulk material. The assembly includes a grabber on an overhead crane to pick up the metal piece once located. The hopper comprises air doors and air roofs to keep off from smell spreading into the room. The organics that are extracted from the waste are free of plastics and other packaging material.

  • Patent number: 6244427
    Abstract: A drive roller has a brushless D.C. motor with a stator or armature mounted on a fixed shaft and directly driving a 16 pole permanent magnet rotor mounted inside a roller tube. A motor controller drive supplies three-phase power to a Y-connected three phase winding having three groups of two coils, forming twelve electromagnets which drive the rotor. The modular motor is readily built in one inch increments to supply one lb-in of torque for each increment. The controller operates at a relatively low frequency of 15-75 Hz. Hall effect sensors provide feedback on motor speed and position. The armature laminations are relatively thick because of the relatively low power necessary to drive the motor and the resultant relatively low eddy currents present in the motor core. A 4.0 lb-in torque motor with a rotor and stator length of four inches will draw approximately 0.8 amps consuming about 15 Watts.

    Abstract: An apparatus for optimizing the gap between objects on a roller conveyor is provide which enables independent precise speed and acceleration control of individual rollers and articles carried thereon using small, relatively inexpensive motors and control equipment. The present invention consists of adding a differential drive to the roller, arranged so that the majority of the power is transmitted from a common drive through a low ratio input of the differential drive of each roller. A smaller motor capable of more precise control is connected to the high ratio input of the differential drive of each roller.

    Abstract: A conveyor for sorting and arranging in single file randomly received articles is disclosed. The unscrambling device has an acticle conveying surface consisting of skewed rollers divided into a number of zones arranged in tandem along the conveyor. The rollers in each zone from infeed to discharge are driven at increasingly higher speeds with the zones overlapping in such a manner that abrupt speed changes occur in steps both lengthwise and laterally of the conveyor. The articles are biased to one side of the conveyor which side is equipped with an article contacting rail divided into segments at least some of which are inclined to impart a jostling effect to the articles.

  • Patent number: 4274780
    Abstract: Objects to be stacked on a pallet or packaged without using a pallet, are transported by a conveyor to an inlet roll track where the objects are assembled into rows, from the inlet roll track a row of the objects is transferred to an intermediate support member where a layer of rows of the objects are collected and then picked up by a forklift device for movement to a pallet or a stack support. The inlet roll track is made up of a number of rollers which can be driven at variable speeds with the rollers most remote from the inlet to the inlet roll track moving at the lowest speed. Alternatively, the rollers of the inlet roll track can be arranged in groups with each group operating at a different speed and capable of being switched on and off separate from the other groups. The stack support can be moved vertically so that the forklift device places each layer on it in about the same horizontal plane as the stack is built up.

  • Patent number: 4219114
    Abstract: A conveyor stop structure arrests the forward motion of a selected article carried by a belt driven live roller conveyor and simultaneously disengages an associated roller from powered engagement with the belt. The stop structure includes a stop connected to conveyor frame members for upward pivotal movement, and a roller contacting cam for raising a selected roller from powered engagement with the belt. The stop has an angled lower portion which receives a bottom leading edge of the article and lifts at least the bottom leading edge from contact with another roller as the article swings the stop rearwardly and upwardly.

  • Patent number: 4111412
    Abstract: A conveyor for separating and aligning glass sheets moving along a sheet movement path includes a plurality of cylindrical rolls skewed relative to the movement path to displace the advancing sheets toward a side of the conveyor. At the side of the conveyor the sheets are aligned by an endless belt rotating through a path parallel to the sheet movement path. Each successive roll in the direction of sheet advancement has increasing peripheral surface rotational speed to separate the advancing sheets.

  • Patent number: 4006815
    Abstract: An article transporting conveyor having live rollers driven through power transmission rollers having a slip or non-slip connection with the live rollers in which the presence of the weight of articles to be conveyed increases the drive between the transmission rollers and the live rollers, but if the conveyor should experience a line blockage the transmission rollers would continue to function while the live rollers would slow and stop turning, thereby protecting the articles from damage and assuring minimum pressure on the articles from the drive transmission rollers.

  • Patent number: 3980170
    Abstract: A drive system is disclosed which is particularly suitable for use in the glass industry. The drive system is for a plurality of conveying mechanisms to support and to move a load which may be discrete glass objects or a strip or sheet of glass. An electrical line shaft is created by using a plurality of squirrel cage synchronous motors which are connected to drive the conveying mechanisms, whether they be transfer mechanisms for discrete objects or rolls for conveying the strip of glass. One or more electrical inverters supply power to the motors so that not only are the motors operated in synchronism but also in phase register. Thus where discrete glass objects are conveyed the phase register of the transfer mechanisms between glass machines prevents glass breakage, and where rolls are conveying a strip of float glass, the phase register prevents difference in phase rotation of the rolls which could mar the surface of the float glass.
